[PATCH AUTOSEL 5.18 78/93] Bluetooth: btusb: Remove HCI_QUIRK_BROKEN_ERR_DATA_REPORTING for QCA

[Sasha Levin <sashal@kernel.org>]

From: Zijun Hu <quic_zijuhu@quicinc.com>

[ Upstream commit 1172c59f451f524a14bac5e7b047781883dfe441 ]

Core driver addtionally checks LMP feature bit "Erroneous Data Reporting"
instead of quirk HCI_QUIRK_BROKEN_ERR_DATA_REPORTING to decide if HCI
commands HCI_Read|Write_Default_Erroneous_Data_Reporting are broken, so
remove this unnecessary quirk for QCA controllers.

The reason why these two HCI commands are broken for QCA controllers is
that feature "Erroneous Data Reporting" is not enabled by their firmware
as shown by below log:

@ RAW Open: hcitool (privileged) version 2.22
< HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0
> HCI Event: Command Complete (0x0e) plen 68

      3 slot packets
